I’m an adherent to oxy/propane (Hoke type) torches, but when I
teach the choice is often between Prestolite (and Goss) and Smith
acetylene/air. I much prefer the Smith-- it seems more precsise
and “feels” better than Prestolite or Goss. The tips seem to
cover a wider range and attach to the torch body in a more
straight forward and machined way. Additionaly, when you drop a
Prestolite on a hard floor, the plastic handle can sometimes
break. Another problem is that this handle often loosens and for
some reason you can never seem to retighten it as well as before.
One advantage to the Prestolite type of handle is its size: less
hand fatigue and the fact that it’s plastic means that on a cold
winter morning it’s fairly comfortable to hold.
Good luck, Andy Cooperman
